提高舆论引导能力,是地方党报肩负的使命,是改进党的思想理论宣传教育的重要内容。而要提高地方党报舆论引导能力,就要在充分发挥地方党报优势上做文章。本文从发挥政治资源优势,创新舆论引导手段、把握新闻规律三个方面对如何发挥地方党报优势,提升舆论引导能力进行了阐述。     

旅游地环境承载力合理阈值量测研究新探索

纵观现有旅游地环境承载力理论与应用研究,成果主要集中在从不同角度对其概念、量测指标体系及在旅游管理与规划领域的运用进行探讨,其阈值量测则以静态极值为主,且个案居多,表明学界尚未形成统一的理论研究范式与共同纲领。更为重要的是,旅游地合理承载力阈值研究仅作为概念获得共识,定量分析尤显不足。基于上述原因,本文从复杂系统理论出发,在深入分析旅游地环境承载力与生命周期之间耦合关系的基础上构建了旅游地动态演化模型及其理论研究框架。该研究一方面为探寻旅游地环境承载力理论提供一种新思路,另一方面解决了环境承载力合理阈值量测这一旅游地可持续发展的核心问题。     

森林公园旅游环境承载力评估——以重庆黄水国家森林公园为例

森林公园旅游环境承载力评估是一个复杂的问题。一方面受到诸如景区自然环境特征和组成结构、景区经济环境背景和社会文化环境、旅游者的行为特征及人口学特征等诸多指标的影响,另一方面又必须考虑景区旅游淡旺季的季节性波动。面对如此广泛的影响因素,本文选取重庆黄水国家森林公园进行实证研究,运用动态改进层次分析法(ADIHP),从承载力指标构架、旅游地空间区划、旅游地季节性波动三个方面,对森林公园旅游环境承载力进行了研究,通过对重庆黄水国家森林公园旅游环境承载力的综合评估,为森林公园景区的优化设计、规划与开发提供了较为科学准确的理论依据和实际参考价值。     

Gas breakthrough pressure for hydrocarbon reservoir seal rocks: implications for the security of long-term CO2 storage in the Weyburn field

This paper reports a laboratory study of the gas breakthrough pressure for different gas/liquid systems in the Mississippian‐age Midale Evaporite. This low‐permeability rock formation is the seal rock for the Weyburn Field in southeastern Saskatchewan, Canada, where CO₂ is being injected into an oil reservoir for enhanced recovery and CO₂ storage. A technique for experimentally determining CO₂ breakthrough pressure at reservoir conditions is presented. Breakthrough pressures for N₂, CO₂ and CH₄ were measured with the selected seal‐rock samples. The maximum breakthrough pressure is over 30 MPa for N₂ and approximately 21 MPa for CO₂. The experimental results demonstrate that the Weyburn Midale Evaporite seal rock is of high sealing quality. Therefore, the Weyburn reservoir and Midale Beds can be used as a CO₂ storage site after abandonment. The measured results also show that the breakthrough pressure of a seal rock for a gas is nearly proportional to the interfacial tension of the gas/brine system. The breakthrough pressure of a CO₂/brine system is significantly reduced compared with that of a CH₄/brine system because of the much lower interfacial tension of the former. This implies that a seal rock that seals the original gas in a gas reservoir or an oil reservoir with a gas cap may not be tight enough to seal the injected CO₂ if the pressure during or after CO₂ injection is the same or higher than the original reservoir pressure. Therefore, reevaluation of the breakthrough pressure of seal rocks for a given reservoir is necessary and of highest priority once it is chosen as a CO₂ storage site.     

价值共创:景区游客管理理念转向及创新路径

在可持续发展思潮的影响下,游客管理重新成为研究的热点。国内外景区游客管理理论先后出现了"以环境保护为导向"和"以游客为中心"两种重要思想,但二者均忽视了游客在自我管理中的能动性及其对景区可持续发展的重要意义,因而削弱了二者的实践价值。价值共创理论作为强调企业和消费者基于价值互动的新理论,为重新审视和创新景区游客管理理念提供了新路径。在价值共创式游客管理框架模型中,景区游客的偏好管理、容量管理、体验管理和行为管理等界面,构成了价值共创式游客管理理念模型的四大板块。景区为游客搭建对话与互动的平台,并构建个性化体验环境,推动四大板块的管理创新与联动,从而实现生态价值、体验价值和经济价值的最大化。     

城市旅游环境可持续承载的管理创新研究

伴随着中国旅游业的迅猛发展,旅游环境问题日益突显,超载现象日益严重。本文结合管理创新的包容性、引导性和推动性思想,探讨城市旅游环境可持续承载问题,为城市旅游环境可持续承载提供竞争优势和持续竞争来源。文章通过对旅游环境超负荷使用的原因分析,提出城市旅游环境可持续承载管理创新的内涵,构建了旅游环境可持续承载管理创新的生成机制,探讨了内外部种子基于"问题探索式"的管理创新,阐述了城市旅游环境可持续承载或承载可持续性的管理创新模式,旨在为旅游环境承载力"超载"问题的解决提供新的角度,提升城市旅游环境的承载能力,调节"承载强度",促成其从"承载潜力"向"承载实力"转化,实现城市旅游环境的可持续承载。     

Climate change and the expansion of the Scythian culture after 850 BC: a hypothesis

In south-central Siberia archaeological evidence suggests an acceleration of cultural development and an increase in the density of nomadic populations around 850 BC. We hypothesize a relationship with an abrupt climatic shift towards increased humidity caused by a decline of solar activity. Areas that initially may have been hostile semi-deserts changed into attractive steppe landscapes with a high biomass production and high carrying capacity. Newly available steppe areas could be invaded by herbivores, making them attractive for nomadic tribes. The central Asian horse-riding Scythian culture expanded, and an increased population density was a stimulus for westward migration towards southeastern Europe.     

Unfolding the relationship between resilient firms and the region

ABSTRACT

This research explores organizational resilience in four manufacturing firms in four different regions of Norway. While regional resilience has gained attention in research, there have been few studies with a micro-level focus, investigating firms and their distinctive features of resilience. We chose a qualitative multiple-case study approach and employed a critical incident technique to study resilience in selected firms that had experienced external shocks and shifts in regard to changing markets, globalization and advances in technology. Each, however, had managed to continually develop resilience capacity over time. Our framework considered three dimensions of organizational resilience: the cognitive, the behavioural and the contextual. We address how resilience is sustained over time, the evolutionary nature of organizational resilience in firms and how resilient firms relate to the region. We found that all three dimensions of resilience capacity were evident in each firm, but appeared as a complex and unique blend. Furthermore, each dimension was supported by regional ties and affiliations. The findings suggest that organizational resilience is a dynamic capability conditioned by firm–region interactions, which are cultural, social and economic. Regional resilience is built through the contribution of the firm to the economic and social systems of the region.
